Please do the following using the same dataset and field (and using the defaults): 1) create a GA layer using the Wizard 2) create a GA layer using the RBF tool in a model 3) create a GA layer using the the GP RBF tool Right click, each of the GA layers, and choose Properties and then copy the dialog on the Method Summary tab. Are they all the same? -Steve ... View more
